Written by DAN SLOTT Pencils & Cover by STEFANO CASELLI

Training is almost over for our cadets. Some will graduate. Some will washout. And, yes, some WILL die! It all starts here, in the Initiative's biggest story to date! And with the clock ticking on the first class of recruits, get ready to meet the next batch! Including new Marvels, old Marvels, at least one SKRULL, and...THE IRREDEEMABLE GIANT-MAN? Also, with the Gauntlet out of commission, just wait until you meet Camp Hammond's new Drill Instructor... he's a real Taskmaster!

"Killed in Action (Part 1): Snafu"

Henry Pym is revealed to have come up with the 50-State Initiative idea.

Diamondback's last appearance was likely Giant-Size Avengers #1, where she was captured by the Wasp, Black Widow and Ms. Marvel alongside her B.A.D. Girls teammates.

The flashbacks mostly take place during Civil War #1.
